Charmed Kafka K8s tutorial

The Charmed Kafka Operator delivers automated operations management from Day 0 to Day 2 on the Apache Kafka event streaming platform. It is an open source, end-to-end, production-ready data platform on top of Juju. As a first step this tutorial shows you how to get Charmed Kafka K8s up and running, but the tutorial does not stop there. As currently Kafka requires a paired ZooKeeper deployment in production, this operator makes use of the ZooKeeper Operator for various essential functions. Through this tutorial you will learn a variety of operations, everything from adding replicas to advanced operations such as enabling Transcript Layer Security (TLS).

In this tutorial we will walk through how to:

  • Set up an environment using Multipass with MicroK8s and Juju.
  • Deploy Kafka using a couple of commands.
  • Get the admin credentials directly.
  • Add high availability with replication.
  • Change the admin password.
  • Automatically create Kafka users via Juju relations.
  • Enable secure connection with TLS.

While this tutorial intends to guide and teach you as you deploy Charmed Kafka, it will be most beneficial if you already have a familiarity with:

  • Basic terminal commands.
  • Kafka concepts such as replication and users.
